geasaa ToaZZ wkomitmm concern Be it known'thatwe, SAMUiin HfCocKn 'andJOHN O.,MILLER, citizens of the Unlted States, residingat Greenville, in the county of Greenville, and State of South Carolina,

in Spring-Supports for Looms, of which the following is a specification.

This invention relates to spring supports forthe rests for looms, and isadapted par ticularly to be used in connection with the harness structure of. dobby looms.

The primary objectofthe invention is to provide means of simplified and improved nature. for supportingthe lower ends ofthe harness springs from theframeof the loom,

thus obviating theuse of spiders or otherdevices upon the floor and permitting of access being had to the floor surface. beneath the loom frame for cleaning orother purposes.

further-object of the invention is to provide asupport of the. character stated .which is; adaptable to loom frames of different sizes, which may be readily adjusted and secured to such frames, which permits of a. variety of adjustments in the spring supporting. device, and which will prove highly practical and efiicient in use.

With these and other objects in view, the

inventionfconsists of the featuresof con-- struction, combination and arrangement of it parts, hereinafter fully described and claimed, reference being had to the accomf panying drawing, in which:

Figure 1 is a front elevation of a conventional type of loom and illustrating'as ap plied thereto the stand or spring support constructed in accordance with the invention, V

Fig. 2 is an enlarged longitudinal sectional view taken through the support,

Fig. 3 is a top plan view of the support detached from the loom frame, and

Fig. 4 is a transverse sectional view taken wardly through the underlylng portion of substantially upon line 4-4 of Fig. 3

Referring now to the drawing,, there is shown a part of a loom frame indicated at 5, and this frame is of the usual type and employs harnesses 6 and 7 of familiar construction. The lower or bottom bars of the harnesses have connected thereto the upper ends of the harness springs indicated at 8;

These springs, as is well known, mustbe connected at their lower ends to some rigid support .or structure, and most instances 1 srnrne-surronr ronrooars.

they are attached to spiders, hooks or other securing devices attached to the floor.

The support of the present invention is indicated generaly at 10 and one'of these supports'is provided for the springs at each side of the harness structure. Each support comprises a pair of metallic barsof light weight but rigid construction arranged at their adjacent ends in overlapping relation as shown. The sections of the bars are indicated at 11 and 12 respectively, the said section 11 having its outer end extended downwardly at substantially right anglesas at 13, and an' outwardly extending foot 14 is formed at the lower end of this angular portion 13." The foot 14 is apertured as shown and is adapted to fit up beneath the under surface of cross rail or bar 15 at the forward end of the loom frame; a screw or jbolt passing through the aperture 111 sald foot to secure the same rigidly thereto. The outerend of the bar section 12 is provided inwardly from'its extremity with an upstanding plate portion 16 adapted to lie flat against the rear rail or bar 17 of the 100m frame, and, screws or bolts 18 passing.

through said plateportion will Secure the latter rigidly to the said bar. The body of section 12 protruding beyond. the plate portion lhflconstitutes a lip 19 to, engage beneath the rail 17 to prevent the support moving upwardly andto assist in resisting upward pull delivered to the support by the harness springs. 1 I

The bodyportion of section 11 upon its upper face is channeled as'at 20 to receive the adjacent end of the section 12 of the support. By thus channeling the section 11, it

is obvious that lateral thrusts of the sections will. be resisted and movement of the said sections laterally to each other will be overcome. The overlapping end of the section 12 is provided with a longitudinal slot 21 to receive a stud or bolt 22 extending upsection 11, and it will be understood that this construction enables thesaid sections '7 to be adjusted longitudinally relative to each for the purpose of attaching the lower ends 1 of the harness springs to the said support.

This spider has laterally projecting hook members 24 at its sides and feet 25 at its extremities, and these feet seat within longitudinally disposed channels or depressions 26 in the upper surface of support section 12. The said support section is provided with longitudinally disposed slots 27, through which extend bolts 28; the said bolts also passing through openings in feet 25 of the said spider. From this construction it is obvious that adjustment of the spider longitudinally of the support may be readily and accurately made, and the said spider Will be held positively against accidental movement or displacement upon tightening of the nuts of bolts 28. By reason of the channels or depressions 26, lateral movements of the spider upon the support section would be resisted.

A desirable and important advantage of our construction of spring supports is that it enables shorter springs to be used, thus reducing the cost of the springs employed and securing greater economy in the operation of the loom.

The foregoing is a description ofthe invention in its preferred embodiment, however, this disclosure is not to be regarded as a limitation of the invention, as variations may be made in the minor details of construction, proportion and arrangement of parts Without departing from the invention as defined by the claims.

Having thus fully described our invention, we claim:

1. In a loom, in combination, a loom frame having front and rear rails, a support, the said support being formed of relatively adjustable sections and secured to the said rails, and means on said support for attaching springs thereto.

2. In a loom, in combination, a loom frame having end rails, a support extending between and secured to said rails, said support comprising longitudinally adjustable sections, and a spring attaching spider mounted upon said support for adjustment longitudinally thereof and of the loom frame.

3. In a device of the classdescribed, a support having recesses in one face thereof, the said support having alined slots communicating with said recesses, a spider, feet on said spider resting in said recesses and being limited against lateral movement by the side walls of the said recesses, and bolts extending through said slots and connected to said feet.

l. In a devire of the class described, a support comprising bar sections, the said sections being arranged in overlapping relation at their adjacent ends, means cooprating with said adjacent ends for holding said sections rigidly together, and means at the outer extremities of said sections for attaching the same to a suitable base.

In a device of the class described, a support comprising a pair of bar sections, one of said sections being of slightly greater width than the other and being provided in its upper surface and near one end with a depression of equal width with the other of said sections, the said other section adapted to seat within said depression, the said other section having a longitudinal slot in its end, a stud extending through said slot and the adjacent portion of the first mentioned bar section, and means on one of said sections for supporting a spring securing device.

6. In a device of the classdescribed, a support comprising bars arranged at their ends in overlapping relation, means connecting said overlapping ends whereby longitudinal adjustment of the sections may be made, an angular leg at one end of one of said sections, a foot secured to said leg, a )late portion extending upwardly from the outer end of the other of said bar sections and inwardly from the extremity thereof, and the said plate portion and said foot being provided with apertures to receive securing means.

In testimony whereof we aliix our signatures.
